Find the area of the shape below

Hello! 80

Step-by-step explanation:

What I did was find area of the shape all together without the cut out square and that was 96 because 12 × 8 = 96 then I found the area of the square 4 × 4 = 16 so I just subtract that by 96 and then thats are answer so...

96 - 16 = 80 so 80 is our area HOPE THAT HELPS!

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
